   Does long-term exposure to blue light affect subjective affect and comfort?

   • For example, a research conducted in 2017 found that short-term exposure to monochromatic blue light decreased lower-frequency electroencephalogram bands while long-term exposure induced an increase in lower frequency bands 35. The effects of long-term light on subjective affect and comfort should be investigated in future.

   Does light exposure affect our alertness and cognition?

   • Since light exposure during morning and daytime influences our alertness and cognition 42, 43, we deemed capturing these behaviours essential for the sake of the completeness of our inventory. However, the possibility of improving the reliability should be investigated further by adding more appropriate and relevant items to this factor.
